Title: Divergence-conforming discretizations and efficient multigrid methods for incompressible flow problems
Abstract: Divergence-conforming finite elements provide a straight-forward means to obtain strongly divergence free solutions for incompressible flow problems. For Stokes flow, they have to be combined with discontinuous Galerkin methods for consistency. The methods can be embedded into a cochain complex framework in order to guide the analysis. We discuss multilevel methods with Schwarz type smoothers based on these concepts. We show the application of such methods to coupled Darcy-Stokes problems.
